COVID-19 has created havoc all over the world. Everyone wants to know when this pandemic is going to end, is there a vaccine available that can help curb the spread.
Well, currently, no vaccines have proved to be productive work to protect people from this scary virus, but attempts by researchers are going on, and multiple candidates are under progress. About COVID-19 vaccine trials in China, there are five vaccine candidates. Preliminary clinic trial results were positive and expected to test in a Phase 3 trial in Brazil, said by China’s vaccine maker Sinovac Biotech.
On June 24, 2020, this trial agreement was signed between the two countries by the G42 and the Sinopharm Group, a leading research-based pharmaceutical company and affiliate of CNBG. This collaboration is not the only vaccine at the phase 3 stage, but also the University of Oxford has begun a phase 3 trials on its vaccine with 30, 000 participants in July.
Globally, the researchers are putting efforts to find a corona virus vaccine. However, it is still unsure whether a vaccine will be available to the public, but there is a hope to produce it by early 2021.
Vaccines undergo multiple phase trials to ensure effectiveness and safety. According to the US Centers for Disease Control and Prevention, clinical development takes three phases. Phase 1 includes small groups of people to get the trial vaccine. A larger group with people having similar characteristics is involved in the phase 2 trial. A phase 3 trial can be a critical moment which may use to confirm results from phase and phase 2 vaccine trials.
The report by the World Health Organization reveals that there are 16 candidate vaccines in clinical evaluation and a further 125 in preclinical evaluation.
And while scientists and researchers are in a battle to win the Coronavirus vaccine, there is still no guarantee of how and when one will find.
